This invention relates to an oven construction and more particularly to an oven and door therefor composed of a plurality of nested shells and a hinge for the oven door.

It is an obj cct of this invention to provide a novel hinge mountin for connecting an oven door to an oven, whereby both the door and the oven are formed of aplurality of nested shells.

Another object of the invention resides in the provision of a simple'and inexpensive hinge structure for securing a hollow oven door to an oven having hollow walls.

A further-object of the invention has to do with the utilization of the innermost shells of a multi-shell oven and door therefor, to define a hinge structure for securing the door to the oven.

A still further object of the invention-is to utilize the inner shell of a multi-shell oven to define a. stepped ledge or seat for accommodatin an oven door aswell as a hinge structure or the door.

In accordance with the general features of this invention there is provided an'oven and door therefor, each compbsed of a plurality of nested shells, the innermost shell of the oven being bentto define the end of the oven cooperable with the door as well as a portion of the hinge forthe door and the innermost shell of the doorbeing extended-to define the edge of the *door adapted to rest against the end of the oven as well as another the ot er hinge portion.

Other objects and features :of this invention will more fully appear from the following detailed description taken in connection with the accompanyingdrawings which illustrate a single embodiment thereof, and in which Figure 1 is avfragmentary vertical sectional view through an oven construction embodying the features of this invention;

Figure 5 taken on substantially the line VI'?.-VI .of Figure 2 illustrating the position of the door when the oven is open. As shown on the drawings: 5 The reference characterlO designates generally an .oven proper, having one end formed open for cooperation with a door 11 adapted to be hingedly connected thereto. The oven, proper,comprises "a plurality of nested shells which are preferably punched from sheet metal and which are designated These shells are spaced from each other to rovide a plurality of air compartments 1n the wells of the oven 10. It is, of course, to be understood thatcwhile I have illus of the oven lOas well as the walls of the door 11 as being madeu of three nested shells, that the invention is not to be thus limited for obviously, the

number of shells used maybe varied in accordance with the particulandesires or requirements of the manufacturer of the oven. Also, it is to be noted that while the oven illustrated is designed-especially for use in connection with an electric stove, the invention may be used in any othertypes of ovens without deviating from the features Thefdoonll of the oven, is also as pie viously pointed out, made up of a'pl'urality of sets of-metallic shells which are designated by the reference'characters l5, l6

and 17.

The outermost shell 12 of the oven is spaced from the middle shell 13 by means IVI V of Figure 2 looking in the direction by the reference characters 12, 13 and 14.

of an angular spacing element illustrated in Figure 1 and designated by the reference character 20. The inner shell 14 of the oven is spaced from the middle shell 13 by means of'the outermost end of the middle shell 13 which is bent in a diagonal direction and toward the shell 14 for cooperation with an annular flange portion 22 formed inte gral with the inner shell 14. This bent outer end of the shell is designated by the reference character 21, and willbe more fully discussed hereinafter.

The outer end of the innermost shell 14 is bent in a direction toward the outermost shell 12 to form the flange portion 22 which is at substantially right angles to the shell 14, a diagonal portion 23 and another flange portion 24 parallel to portion 22 terminatin to the shell 14 and adapted to overlap the in an outside strip 25 disposed parallel outer edge of the outermost shell 12. It will be evident from the drawings that the three flange portions 22, 23 and 24 serve to completely enclose the open ends of the spaces between t-he nested shells 12. 13 and 14 as-well as to tion for the door 11 when it is in its closed position.

The innermost shell 17 outermost end bent into of the door has its tion 27 which portions are of a similar shape to the three portions 22, 23 and 24 of the inner shell 14 of the oven. In fact, when the door is in its closed position the portion 26 will engage the portion 22, the portion 27 will engage the portion 23 and the por tion 28 will engage the portion 24, as is best shown in Figure 4. Also, the portion 28 terminates in an overlapping strip 29 disposed substantially parallel to the shell 17 and adapted to overlap the outer surface of the outer shell 15 of the door as shown in Figure 4. Obviously, the diagonal contacting portions 23 and 27 of the oven and door respectively enable a more nearly seal-tight engagement of the oven by the door.

It will now be noted that the bent portion 21 comprising the outer end of the intermediate shell 13 of the oven is so formed as to abut both the portions 22 and 23 of the innermost shell at the junction of these portions. Also, the intermediate shell 16 of the door is provided with an outwardly bent edge 30 for engaging and abutting the portion 28 on the inner shell 17 of the door.

Referring to Figure 1 it will be observed that the middle shell 16 of the door is separated from the outermost shell 15 by means ofprotuberances 34 and 35 formed integral with the middle shell and arranged to contact the inner surface of the outer shell 15.

A bolt 36 extends through the three shells on the door as well as through the protuberdefine a stepped seating por- 4646 (Figs. 3 and 5).

pressed portions flange portions'26. and 28 and an intermediate diagonal por-I the provision of ance 34 and is adapted to have'threaded on its outer end a handle 37 for the door.

The rear part of the oven proper has a plate 38 disposed between the middle shell 13 and the outer shell 12 which is adapted to be bolted to a side 39 of the range or stove carrying the oven. Also, the bolts 40 extend through suitable openings of the innermost shell 14 and middle shell 13 and are threaded into the'plate 38 for fixedly anchoring the plate to the shells of the oven.

Also, the inside surfaces of the shells 14 and 17 may be chromium plated in order to depressed inwardly at the bottom of the /oven wherethe hinge connection is to be established as indicated at 45 (Figs. 3 and 6). The ends of this depression 45 are slotted and depressed still further into the air compartment behind the shell 14 as indicated at Each of the de- 46, as will be evident from Figure 5, terminates at its lower end in the flange 25. The two depressed portions 46 are adapted to cooperate with spaced hinge portions on the oven door which take the form of curved extensions 47 formed integral with the vertical portion 28 of the inner shell 17 of the door. Each of the pressed down extensions 47 to the door has a curvature conforming to that of the depression of the corresponding depressions 46 so as that as the door is swung to its full open position the extension 47 will move easily over the curved surfaceof the depression 46 as is evident from Figures 5 and 6. Furthermore, it will be observed that the vertical portion 28 of the shell 17 has an outwardly pressed portion 48 adapted to abut the inwardly de- '24 of shell 14 (Figure 5).

The depressed portion 45 of the vertical portion 24 of shell 14, as best shown in Figure 6, terminates in a semi-cylindrical projection 50 having its outermost surface flush with the normal outer surface of the portion 24. This semi-cylindrical extension 50 extends the full distance between the hinge projections 47-47 on the door so as to accommodate a hinge-bolt 51 extending through the semi-cylindrical portion 50 and having its ends passing through the interior of the extensions 46-46 on the door. It is to be noted that the hinge-bolt 51 may comprise a single rod or it may comprise two sections, one for each of the hinge extensions 4747 on the oven door.

From the foregoing description it will of the hinge-bolt 51 is mounted in and supported by the semi-cylindrical projection 50 on the vertical portion 21 of the inner shell ll of the oven and the ends of this hingebolt 51 extend through the hinge extensions 47%? of the oven door so that these extensions may pivot about the ends of the hinge-bolt as the door is opened and closed. The cooperating depression 45 and the extension 48 on the shells 14 and 17 res-pectively are provided to insure atight engagement of the oven by the door at the point of the hinge when the door is in its closed position. Then, too, it will be observed that each of the curved depressions 46 is shaped so as to fit around the associated semi-cypression 46 as the door is moved from open to closed position and vice versa.

e cooperating diagonal portions 23 and 27 on the inner shells 14 and 17 of the oven and door respectively are advantageous in that when the door is in its closed position a more effective seal is established between the door and the oven due to the fact that in order for any air or gas to leave or enter the oven it is necessary for such air or gas to follow a tortuous path defined in part by the aforesaid diagonal portions.

Now I desire it understood that although I have illustrated and described in detail the preferred embodiment of the invention the invention is not to be thus limited but only insofar as defined by the scope and spirit of the appended claims.
